ASP.NET Core returns 404 after resetting applicationhost.config

Question

I had a bit of an issue with IIS and I couldn't run my website anymore. I managed to fix it after reinstalling IIS and removing applicationhost.config . Now I can launch the website from Visual Studio but if I surf to it I get:

Not Found

HTTP Error 404. The requested resource is not found.

I don't see any request showing up in the logs either. Why is this happening and how can I fix it?

The applicationhost.config looks like this;

<site name="arnvanhoutte" id="2">
    <application path="/" applicationPool="Clr4IntegratedAppPool">
      <virtualDirectory path="/" physicalPath="E:\OneDrive\Apps\Web\arnvanhoutte\arnvanhoutte" />
    </application>
    <bindings>
      <binding protocol="http" bindingInformation="*:52250:localhost" />
                <binding protocol="https" bindingInformation="*:44397:localhost" />
    </bindings>
  </site>
  <siteDefaults>
    <logFile logFormat="W3C" directory="%IIS_USER_HOME%\Logs" />
    <traceFailedRequestsLogging directory="%IIS_USER_HOME%\TraceLogFiles" enabled="true" maxLogFileSizeKB="1024" />
  </siteDefaults>
  <applicationDefaults applicationPool="Clr4IntegratedAppPool" />
  <virtualDirectoryDefaults allowSubDirConfig="true" />

This is the log after I run iisexpress.exe /config:"applicationhost.config" /site:"arnvanhoutte" /apppool:"Clr4IntegratedAppPool" /trace:error
